Fair Billing Policy

At Slack, you only get billed for the people who use it each month. And if someone you’ve already paid for becomes inactive, we’ll add a prorated credit to your account for the unused time. Because billing should be fair — and we like you.

Commonly asked questions

You can use your credit card to pay for any plan. If you sign up for an Annual subscription and plan to spend at least $2,000, we can invoice you annually. Visit the help center for more information or Contact us to start the process.

Every day we check to see if everyone on your team is active. If they have been inactive for a period of time, we stop charging you for that person and add a prorated credit to your account for the time you’ve already paid. You’ll always and only be billed for what you use — fair and square!

Once your team signs up for a subscription plan, we’ll draw against your credit balance until it runs out. Only then will we start charging your subscription to your credit card. As long as you sign up for a subscription plan before the expiration date, those credits are yours to use until they’re all gone.

We’ll make a one-time, prorated charge to your credit card to cover your new team member’s account for the remainder of the current billing period.

As an example, suppose your team is on the “Standard plan,” which costs $8 per active user per month when billed monthly. You add a new team member 10 days into your billing period and there are 20 remaining days in the month. The per-day cost for each user is $8 / 30, so we will make a one-time charge of $5.33 ($8 / 30 days * 20 days) to your team’s credit card on file.

Team Owners can change the team’s subscription level. There are two options when downgrading from a paid plan to the Free plan:

You can downgrade to the Free plan immediately. If there is more than one day until your renewal date, we will prorate the remaining balance on your account and hold it for your team as a credit. You can use that credit towards a reactivation of your paid subscription in the future.

We can automatically downgrade you to the Free plan at your next renewal date. Your subscription will remain active at its current level through the end of the billing period that you’ve already paid for.
